Mass spectrometer enhances SwRI’s USGR automotive catalyst testing

Green Car Congress

Southwest Research Institute has expanded its capability to evaluate internal combustion engine aftertreatment catalysts, integrating an existing SwRI technology with a mass spectrometer. Different chemical structures absorb light at specific wavelengths, producing unique spectral fingerprints.

Light duty RCCI can deliver engine-out Tier 2 Bin 5 NOx; potential for 52% gross indicated efficiency

Green Car Congress

Rolf Reitz of the University of Wisconsin found that reactivity controlled compression ignition (RCCI) ( earlier post ) in a light-duty engine can meet Tier 2 Bin 5 NO x levels without aftertreatment, while offering a 4% improvement in fuel consumption and 7.3% Their paper is published in the International Journal of Engine Research.

ORNL study finds multi-mode RCCI can offer 15%+ fuel economy improvements across multiple light-duty driving cycles

Green Car Congress

Their paper is published in the International Journal of Engine Research. Among their findings were that multi-mode RCCI has the potential to offer greater than 15% fuel economy improvement over a 2009 gasoline PFI baseline over many light-duty driving cycles, despite the lack of complete drive cycle coverage for RCCI mode.
